Not sure if this is the root of your problem, but spaces in your file path can lead to unwanted (or no) results in your code. If you can, replace spaces with underscores or, better yet, camelCaseText. Also, it is a good habit to use r in your path so Python reads it as a text string:

arcpy.env.workspace = r"X:\311\Obtaining GIS Data\TaxParcels.gdb"
